Supporting Women in the UK Armed Forces Who Consume Alcohol at an Increased Risk: Refining the DrinksRation Platform - Study Protocol

There are 2.5 million AF veterans in the UK (defined by the British Government as those who have served in the military for at least one paid day), of which 11% are estimated to identify as female. Female veterans have served within the AF for over 100 years. While their valuable contribution has been recognized, military culture, together with evolving Service requirements, have had a significant impact on the health and well-being of many. Yet, there is a dearth of evidence on the impact of alcohol use on female veteran health.

The limited existing evidence suggests that female veterans' alcohol use is increasing and that they are significantly more likely to report symptoms of hazardous drinking when compared with female civilians. Increased rates of hazardous drinking were also observed by Palmer and colleagues (202), who found that half (49%; n=389 of 779 female veterans) were misusing alcohol at a hazardous or higher level which is considered harmful to their health. To place this into context, the UK Chief Medical Officer recommends that everyone does not regularly drink more than 14 units per week, to keep health risks from drinking alcohol to a low level.

Alcohol misuse often co-occurs with common mental health disorders including PTSD, anxiety, or depression, and alcohol is frequently used as a coping mechanism. Common mental health disorders are more common in females than male veterans. Research has also shown that female veterans face barriers to accessing mental health support, often due to misusing alcohol. Ultimately, while female veterans drink less than male veterans, their rates of hazardous drinking are higher than the general population putting them at increased risk of poorer health.

The impact of alcohol misuse among female veterans on the wider society (e.g. health care utilization, productivity, and welfare) is unknown. In England, heavy drinking (deemed as drinking more than 14 units of alcohol per week) is estimated to cost the National Health Service (NHS) £3.5 billion per year (3.6% of its annual budget) and is more common in people with mental health difficulties, Since female veterans drink more than their civilian counterparts, the relative costs are likely to be even higher. Innovative solutions are urgently required.

In recent years there has been a growing treatment gap in the UK, with patients waiting longer for treatment and support for alcohol misuse. To overcome this gap, the investigators developed the DrinksRation platform (www.drinksration.app), an automated brief digital intervention designed to support help-seeking veterans in managing and reducing the amount they drink. DrinksRation is unique in that the app content is tailored using behaviour change techniques to promote positive changes in behaviour. DrinksRation is the only app targeting alcohol misuse in the UK AF. It is designed to (1) overcome geographical limitations; (2) use wearable technology (e.g. Fitbit, Apple Watch) to inform decision-making and personalization; (3) avoid the stigma associated with receiving help in person; and (4) provide convenience since users can use the app as they prefer (discretely or openly). The app is freely available via Apple and Google App stores. The app has received support and endorsement from Combat Stress and is currently being trialled in serving personnel. DrinksRation is supported by a robust evidence base, including a randomized controlled trial which demonstrated that the app is efficacious in reducing alcohol consumption.
